I've tried the Transfer Factor from my doctor and this is better - and cheaper!

I was diagnosed with cytomegalo virus which causes memory loss. My doctors advised me to start taking Transfer Factor. The brand they sell costs $75.00 a bottle!! Although it helped tremendously, I just couldn't afford it anymore. So, I trued Source Naturals - it works better and the cost if easier to swallow, too!

Nice product

The 125 mg dosage is exactly what I need for daily support, and the capsule size makes them very easy to take. I appreciate the clean list of ingredients and the fact that this 60-capsule bottle offers great value for the price. It’s a reliable addition to my wellness routine.

Suggested by nutritionist

It’s suggested by my nutritionist as a good quality transfer factor with good ingredients. The size isn’t big. The immune system benefits from it. I haven’t started taking it, I hope it taste good. It was prescribed by my nutritionist for me and for my 6-year old son

Great quality

It was more of an experiment for me to order this supplement. But I am quite satisfied with my results, which I have seen in two months. Will try out more.
